PIN.

Application filed March 14, 1922. Serial No. 543,614.

T aZZ whom it may concern:

Be it known that 1, WILLIAM A. JoHNson,

a citizen of the United States, and a resi dent of Yonkers, lVestchester County, and State of New York, have invented certain new and useful Improvements in Pins, of which the following is a specification.

This invention relates to pins. One of the objects of the invention is to provide a pin that may be readily inserted in material and locked against removal therefrom.

Another object of the invention is to provide a pin that is simple in construction and may be economically manufactured.

Further objects of the invention will appear from the following description taken in connection with the drawings which form a part of this application and in which Fig. 1 is an elevationof the pin with the parts in open position.

Fig. 2 is a transverse sectional elevation taken substantially on line 2-2 of Fig. 1. Fig. 3 is a sectional elevation similar to Fig. 2 but showing the parts in closed or locked position.

Fig. 4 is an elevational view showing the pin inserted in fabric.

Fig. 5 is an elevational view similar to Fig. 4 but showing the pin rotated 180 degrees from the position shown in Fig. 4 and also showing in dotted lines the parts as they are being moved to locking position.

Fig. 6 is an elevational view, broken away, showing a portion of the pin with the parts in their locked position and Fig. 7 is an elevational view similar to Figs. 4 and 5 but showing the pin rotated 180 degrees from the position shown in Fig. 5 and in the position taken when the pin is to be unlocked and withdrawn from the fabric.

The invention may be briefly described as a pin formed from a single piece of wire having a pointed shank, a loop at one end of the shank, a return portion or leg extending from the loop substantially parallel to the shank, the leg having its end portion bent around to cross the shank adjacent the end thereof and reversed to again cross the shank at a point spaced from the end. The parts just described are so constructed and arranged that in use the pin is inserted in the fabric, rotated 180 degrees and moved longitudinally until the fabric by its engagement with the loop end portion of the leg causes the pointed end of the shank to snap by the portion of the loop crossing the shank thereby fastening the end portion of the shank between the two crossing portions of the loop formed on the end of the leg. The pin may be withdrawn by again rotating it 180 degrees about the shank and pulling longitudinally on the pin.

Referring to the drawings the pin illus trated is formed from a single piece of resilient wire and comprises a shank 1O having a pointed end 11, the opposite end of the shank being looped as shown at 12 and a return portion or leg 13 extending from the loop substantially parallel with the shank 10.

The end of the leg 13 is bent to form a transverse portion 14 which crosses the w shank adjacent the pointed end 11 thereof. After crossing the shank the wire has formed therein a nose 15 extending toward the loop 12 or longitudinally of the shank and from the nose the wire again crosses the shank as shown at 16, this crossing portion being concaved as shown in Figs. 2 and 3.

The use of the device is illustrated in Figs. 47 inclusive. The shank of the pin is first inserted in the fabric as shown in Fig. 4-. The pin is then rotated about the shank through 180 degrees to the position shown in Fig. 5 to bring the parts 14 and 16 between the shank and the fabric and is thereafter drawn back lengthwise untilthe loop formed by the parts 14, 15 and 16 is engaged by the fabric. A slight further pull on the pin will cause the point 11 of the shank 10 to snap by the portion 14 of the loop adjacent thereto and the end of the shank will then be positioned over the portion 16 and under the portion 14 of the loop as shown in Figs. 3 and 6.

To release and withdraw the pin from the fabric it is again rotated about the shank 109 through degrees to the position shown in Fig. 7 with the nose 15 and the portion 16 over the shank and a slight longitudinal pull on the pin will then cause the point 11 to snap by the crossing portion 14, engaged thereby whereupon the pin may be withdrawn from the fabric. This snapping of the point 11 by the crossing portion 14 at the end of the leg 13 is due to the fact that the fabric by its engagement with this crossing portion swings it beyond the end of the point 11 of the shank nd permits the point to snap over from one side to the other'of the portion 14. The click or snapping sound is desirable as it is an indication of the fact that the parts have moved to their looking or unlocking position.

The various uses of a pin such as that described will be understood by those skilled in the art but it is particularly adaptable for use in certain forms of jewelry.

Although one specific embodiment of the invention has been illustrated and described it will be understood that the invention is capable of modification and that changes'in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention as expressed in the following claims.

What I claim is 'I. A pin formed from a single piece of wire, comprising a pointed shank, a loop, a leg substantially parallel with the shank and a transverse portion formed on the end of the leg, crossing the shank substantially at the point thereof and a return portion crossing the shank at a point spaced from the end thereof, the return portion being concaved and disposed out of the plane of the first named crossing portion.

2. A pin forinedfrom a single piece of wire, comprising a pointed shank, a, loop, a leg substantially parallel with the shank and a transverse portion formed on the end of the leg, crossing the shank substantially at the point thereof, having a nose extending toward the loop and V return portion crossing the shank and concaved with respect to the shank and to said transverse portion.

3. A pin formed from a single piece of wire, comprisng a pointed shank, a loop, a leg substantially parallel with the shank and a transverse portion formed on the end of the leg, crossing the shank adjacent the pointed end tllGCCOf and a return portion crossing said shank at a point spaced from the pointed end of the shank, said crossing portions being resilient whereby the pointed end of the shank may spring by the said transverse portion. 7

In witness whereof, I have hereunto set my hand this 13th day of March, 1922.

WILLIAM A. JOHNSON.
